Install in 3 Steps and Open Your Account
Installing the cor90 app on Android takes about two minutes from start to first login. iOS access is available through the mobile browser shortcut while a dedicated App Store build is reviewed — the browser version is fully optimized for Safari on iPhone and loads the same lobby as the native app. For Android, the APK is around 30MB, so even a
standard mobile data connection handles the download without issue. Once installed, your existing cor90 account works immediately — no separate registration. New accounts can be created inside the app on the account setup screen.
- Step 1 — Download APK — Open cor90 on your Android browser and tap the Download App button. The APK file saves to your Downloads folder automatically.
- Step 2 — Allow Installation — Go to Settings, then Security or Privacy, and switch on 'Install from unknown sources' for your browser app. This is a one-time step Android requires for APK files outside the Play Store.
- Step 3 — Open and Sign In — Tap the APK file in your Downloads folder to install, then open cor90 from your home screen. Sign in with your existing account or complete the short account setup form if you are new.
